SHUTTLE CHECK AND LOOK FOR LOOMS- Specification of Letters Patent.

ICatented May 15, L906.

Application filed July 18, 1904. Serial No. 217,010.

To all whom it may concern.-

Be it known that I, FRANcIs ARTHUR MILLS, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certainnew and useful Improvements in Sl111ttle Checks and Looks for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention in looms which forms the subject of this patent is directed to the provision of a lever device having a yielding actuating function upon a shuttle-binder whereby the shuttles direct impact upon said lever device causes said lever device to yieldingly press upon said binder to check and lock the movement of said shuttle, and thereby prevent rebounding of the shuttle.

The following description, read in connection with the accompanying drawings,will enable any person skilled in the art to which my invention relates to understand its nature and to practice it in the form in which I prefer to employ it; but it will be understood that my invention is not limited to the precise form, construction, and arrangement of the parts herein illustrated and described, as various changes and modifications may be made in the lever device and its cooperating parts whereby the binder-actuating lever device is caused to have a yielding pressing function upon a binder and the binder on the shuttle by the impact of a side of the shuttle upon the lever device. In cooperation with the yielding function of the binder-actuating lever device the shuttlebinder is provided with yielding means whereby the shuttle is frictionally checked and locked by and under a yielding pressure.

Referring to the drawings, Figure 1 is a top lan view of the left end of a loom-lay and shuttle-box thereon and with one embodiment of my invention applied thereto, the cap-plate or shuttle-guide being removed, the shuttle shown in the position just entering the shuttle-box and the yielding binderactuating lever device in its normal position. Fig. 2 is a similar view showing the shuttle having fully entered the shuttle-box and having operated the yielding lever device upon the binder and the yielding binder upon'the shuttle to lock the shuttle at the end of its movement in the box, the binder being broken away to show the lever device and its engagement with the shuttle. Fig. 3 is a back view of the same, the pivot-mounting of the shuttle-binder and of its actuating-lever device being shown in section. Fig. 4 is a transverse section taken on the line a, b of Fig.2, showing the yielding lever device in the po sition in which it locks the shuttle and showing the contact-face of said device with the shuttle. Fig. 5 shows in section the eccentric for adjusting the lever 20.

Each end of the loom-lay 1 is provided with my improved shuttle-lock and has the shuttle-box thereon, the front wall 2, the capplate 3, the back wall 4, and the picker 5, the picker-stick 6 whereof is adapted to move in a slot 7 in the shuttle-box to actuate the shuttle 8, and the protector-shaft 9, its controlling spring 10, and its standing binder-finger 11 may be and are all of the well-known construction.

The binder 12 is fulcrumed at its outer end on the lay by a bolt 13 and has the usual swell 14 to receive the ingoing shuttle, while at its inner end the binder is caused to rest against the box-wall 4 when the box is empty by the. pressure of the protector-finger, as in Fig. 1. The binder is fulcrumed at its outer end on a bolt 13, and its inner wall is provided with a facing 15 of yielding substance for causing a yieldin binding function upon the shuttle and whic is supplemented by a wear-facing, preferably of leather, 16 to protect the yielding substance and provide a smooth wear-surface.

For actuating the binder upon the shuttle I employ a lever device having a yielding function, and to obtain the required pressing force on the binder I prefer to construct the lever device of a plurality of yielding members, one of which, 17, has its fulcrum on the fulcrum-bolt of the binder and is constructed and arranged to be engaged and operated to separately engage the shuttle and the binder by the ingoing shuttle and actuate the binder with a yielding pressure against the shuttle. For this purpose the primary lever member 17 at its fulcrumed end is fitted within a recess, Fig. 3, on'the under side of the binder and has a binder part 18 rising in a recess at the inner wall of the binder and rovided with a wear-facing 19, preferably of leather. As shown in Fi 4 and by dotted lines in Fig. 3, that part 18 of the lever member 17 which receives the impact of the ingoing shuttle presents a bearing-surface to the whole width of the shuttle, and thereby causes its wear-facing to have an effective binding action upon the shuttle. The free end of this lever 17 rises at a point about the middle of the width of the binder andengages the meeting end of the coacting lever member 20, which being pivoted mediately of its length is caused to be yieldingly pressed against the inner end of the binder by the impact of the shuttle against the primary lever member 17, which in turn forces the coacting member 20 against the shuttlebinder, whereby the shuttle is frictionally checked and locked. To render such action tion of the binder upon the shuttle and the action of the yielding device upon the binder,

and for this purpose the meeting ends of the lever members are provided with a yielding bearing 21, while the shuttle-binder is provided with a yielding bearing 22 for the lever device. As seen in Fig. 1, the lever device is maintained in its normal position by a bladespring 23, attached to the binder, which serves to cause a yielding pressure of the binder upon the shuttle when operated by the lever device, and it also exerts a constant outward force upon the lever device, causing their meeting ends to maintain contact, and thereby causing the impact-lever to be maintained in the path of the shuttle to receive and deliver the impact of the shuttle upon the yielding lever device and the latter upon the binder to check and lock the shuttle under a yielding function, it being understood that the picker-stick moves back and forth free of the impact part of the binder-actuating lever device. The blade-spring also aids to cushion the impact of said lever device upon the shuttle-binder and the latter upon the shuttle. The shoulder ofithe shuttle on entering the box strikes the swell of the binder, forcing its free end outward against the corresponding end of the lever device, which is thereby caused to force the impactlever part into the path of the shuttle, the impact of which forces said impact-lever part outward, causing thereby the lever device to be forced inward against the shuttle-binder and force it against the shuttle. In this action the lever impact part is cushioned upon the shuttle, the lever device is cushioned upon the shuttle-binder, and the latter is cushioned upon the shuttle, so that both the lever "device and the binder are yieldingly pressed against the shuttle to check and lock it"with yielding pressure when at the moment that the shuttle is picked the binderactu-ator lever device is released, which releases the binder pressure. In this operation the free end of the binder engages the protection-finger and by its spring-pressure helps the checking of the shuttle.

It is important to note that while the lever device is caused to act with a yielding, checking, and locking function upon the shuttle the lever device is caused to act With a com pound leverage pressure, the effect of which is to more certainly check and stop the shuttle, because the compound lever device gives increased leverage and renders the lever members sensitive and active in transmitting the pressure of the impact of the shuttle upon the lever device.

I prefer to provide a leather facing for the lever impact part and a like leather wearfacing 24 for the inner wall of the shuttlebox, against which the shuttle is pressedin the operation of checking and looking it.

I prefer to fulcrum the shuttle-binder and the lmpact member 17 of the lever device on the same bolt, as it gives a compact arrangement of these parts and a swingmo vement from the same center. It is also of advantage to place the impact art mediatelyof the length of the primary ever member, because it thereby allows sufficient movement of-the shuttle against the impact part to give the latter its full locking effect of the shuttlebinder upon the shuttle at the time the latter strikes the picker, and to obtain the best results from this effect I have arrangdcushions on the ends of the lever device and also between it and the binder. In using the bolt as a fulcrum common to both the shuttle-binder and the primary lever a bushing 25 is provided for the shuttle-binder bolt, and a separate bushing 26 is provided for said lever, as in Fig. 3. I V

Referring to the lever device, it Will be noted that its member 20 is mounted loosely upon any eccentric pin or stud 27, Fig. 5, which is clamped in a boss 30, fixed to a plate 28, which is secured to the rear side of the lay by bolts 29, which pass through slots in said plate to provide for its adjustment. The eccentric stud is clamped by a shoulder 31 upon the boss by a nut 32 at 'the under side of the boss, and thereby provides a means for adjusting the said leverv member fulcrum out-ward or inward for the purpose of causing it to give more or less yielding pressure upon the binder and the latter upon the shuttle. This adjustment also serves to compensate for wear of the parts of the said lever device. The adjustment of the plate 28 is to allow the binder-actuated end of lever member 20 to beset so as to act against the binder nearer to or farther from the protection-finger, and thereby allow the lever IIO device to be put on looms in which the prov The adjustment of the lever member is made by loosening the nut 32 and turning the eccentric stud to the right or to the left, and thereby causing one of its ends to be moved nearer to or farther away from the end of the binder and its other end correspondingly moved in its relation to the other lever member 17, and in this way the impact of the shuttle upon the face of said lever member 17 causes it to be pressed with more or less force againstthe shuttle-binder, as may be found to give the best results in checking and locking the shuttle. The adjustment of the plate therefore is to position the lever device horizontally to suit the position of the protection-finger, while the adjustment of the lever device laterally upon said plate is to cause it to be pressed with more or less force against the shuttle-binder.
